Further reason to be angry over King's Quest four: the inventory gives you absolutely no hint as to how many times you can use an object. This has twice, now, cost me my game with only a short portion left to play---argh!
First off, when I tried playing the game again a few years ago, I dug once too many with the shovel and, yes, you guessed it, it broke and I was stuck with nowhere to go and nothing to do but start over.
But wait, it gets worse. I tried to beat it again just a week ago and, after working my way through steadily over the course of the week, I got to the end...only to realize that, MY GOD, I had no arrows left to kill Lollette at the end because, apparently, you can only shoot two effing arrows the whole game. Absolutely mindblowing stuff here.
The game was classic, but some parts are just head-scratchingly hard.
